I am seriously considering replacing my Yaris I-4 Toyota engine with a single cylinder from a 2 stroke East German Trabbat. What do you think? A one cylinder, 2 stroke Yaris?

What's wrong with the Yaris engine? BTW, what speed are you going at 2K RPM in 5th gear? Do you know what the final drive ratio is on your car?
Sincerely, Neil

Your Yaris is a great example of an efficient small car.

The Trabant was one of the worst-built POS ever foisted off on the world. Not to mention inefficient and gawdawful dirty out the tailpipe.

If you insist on a two-stroke... look at some of the latest snowmobiles. They are pretty much the pinnacle of that genre... such as it is. I once saw a dune buggy that had been repowered by a Polaris two-stroke snowmobile engine. 0-60 in about 4 seconds. 250 hp out of 450 cc's (IIRC). Insanely fast. Relatively easy on fuel too... in context.

I don't think you'd be allowed to put it on the road.That engine was of the deciding factors for ending production of the Trabant.
